ABSTRACT:
A disk recording/reproducing apparatus includes a spindle control device in which phase control is performed when spindle motor speed is within a predetermined range, and a synchronizing mark detection signal is detected normally. For a composite video signal, a signal synchronization signal may be produced in response to detection of a synchronizing signal within that composite video sinal; phase control may be performed in response to that signal synchronization signal as well. In the absence of one or more of these signals for less than a predetermined time, phase control may be performed based on predetermined phase-difference information. Additionally, an error may be generated if one or more of the above-mentioned signals is absent for longer than a predetermined time.
